United States

A special weather statement may be issued by the NWS for hazards that have not yet reached warning or advisory status or that do not have a specific code of their own, such as widespread funnel clouds. They are also occasionally used to clear counties from severe weather watches [ [http://www.crh.noaa.gov/lmk/product_guide/products/severe/sps.php Special Weather Statement ] ] .

Canada

Special weather statements are issued by the MSC for weather events that are unusual or those that cause general inconvenience or public concern and cannot adequately be described in a weather forecast. These may include widespread events such as Arctic outflows, Alberta clippers, coastal fog banks, areas of possible thunderstorm development, and strong winds such as chinooks and les suetes winds. They are written in a free style and may also reflect warnings in effect near the United States border.

The snow will give localized reduced visibilities and make travel difficult especially along the Yellowhead highway.
